ANTIFRICTION COUPLING-CARRIER.

Application filed February 18, 1915.

This invention relates-in general to rail-l wav dralit rigging andmorespecilically to an uanti-friction carrier tol support the shank ofthe coupler.

ln railway cars, as usually constructed, the coupler shank is slidablysupported on a. carrier iron secured to the sills of the car.

The constant movement of the coupler, when the ear is in use, rapidlyabrades the shank at its point et contact with the carrier 1ron so thatit becomes weakened and unfit for .use and the entire coupler mustfrequently he replaced, although the parts other than the shank may bestillin good condition.

lt is the object ot our invention to pro vide means for supporting thecoupler shankso 'that it is not subjected to abrasion,v whereby the liteof the coupler is materially prolonged. p

Other objects and advantages of our invention will be apparent as it isbetter understood by reference to the 'following specification taken inconnection with the accompanying drawings in which- Figure 1 is avertical section through a portion ot' a car body on a line transverselythereof showing` our invention; installed; Fig. 2 is a vertical sectionthroughthe device on a line normal to the line of Fig. 1; Fig. 3 is avertical section similar to Fig. l, showing a slightly different form ofour invention, and Fig. 4 is a vertical section similar to Fig. 2 ot theform of our 'invention shown in Fig. 3.

Referringr to Figs; 1 and 2 of the drawings, 1 indicates the sills of acar and 2 a carrier yiron secured in any suitable manner to 'the sills.Slidably mounted upon th'eca'rrier iron. 2 is a plate 3 having sideflanges t .extenfling downwardly on either side of the y carrier iron Q,to prevent sidewise movement 'of the plate with respect to the carrieriron, A bolt 5, passingr throughthe 'iangcs ','holdsthe plate 3 incoperative relation with the carrier iron 2. The plate 3 is providedwith downwardly extendingl ribs G which act retainers for the antiySpecification of Letters Patent.

friction rollers 7 loosely mounted between the plate 3 and the carrieriron 2. As will be readily understood, the plate 3 is movablelongitudinally of the carrier iron 3 and frictional contact between theplate and the/carrier iron is prevented by the rollers 7. A plate 8 issuperposed upon the plate 3 and is provided with downwardly extendingyflanges 9 to engage the movement with respect thereto of the plate 8 in-a direction longitudinally of the carrier iron`2 and withupwardly/.extending flanges 10 to engage the sides of the coupler shank'11 and hold it in proper relation therewith. The flanges 10 are slightlycut away at either end of the plate 8,'as indicated in dotted lines inFig. 1, to allow for slight angular movements of the couplershank 11with respectI thereto. The plate S is provided with downwardly extendingribs 12, which act as retainers for the anti-friction rollers 13,loosely mounted between the plates 8 and 3. A bolt 14 is disposed in asuitable opening in the plat-e 8 and passes through a slot l5 in theplate 3, whereby the plate 8 is held in coperative relation with theplate 3, the

8 with respect to plate 3 beingT limited the length of the slot 15. Itwill be 'understood that the plate 8 is movable with respect to theplate Il in a direction normal to the longitudinal axis of the carrieriron 2 and that frictional con- Ifact between the The operation of thedevice will, it is `thought, be apparent without further description ofthe structure thereof. ll/hen the car is in use the coupler shank l1moves both longitudinally and transversely with respect to the car bodv.When the coupler shank 11 moves longitudinally of the car plate 8 willroll upon the plate 3, the movement being, however, limited by the slotdcooperating with the bolt 14. coupler shank 11 moves transversely withrespect to the car body, the plate 3 will roll upon the carrier iron E2,the movement in this case being limited by the sills 1. lt will beunderstood, therefore, our invention all abrasion due to frictionalContact between the coupler shank and the carrier iron is eliminated andthat, therethe wear which has been an inherent defeat in att rigging asheigetofore constructed pviated. y In 2F11;` and 4l we have shown aslightly plate 3 and preventl the v When the that by the use oi plates 8and 3 is prevented irc dierent 'form of our invention in which thecarrier iron 16 is provided with downwardly extending portions 17 and aportion 18 inelineddownwardly from either side towardthe renter.- lnthis form of our invention the plate 3 is provided with downwardlyextending flanges t and a bolt 5 is disposed therethrough to hold theplate in cooperative relation with the portion 418 of the carrier iron16, as in the form previously described. The rollers 19 are journaled at2O in the flanges 4 and therefore remain in their proper relativevpositions regardless of the inclined surface of the carrier iron. The

vplate 8 is provided with downwardly extending anges 21 to preventmovement thereof with respectto the plate 3 in the direction of thelongitudinal axis of the carrier iron and is further provided withinwardly extending flanges 22 which engage beneath the plate 3 and holdthe plate in proper coperative relation therewith. The rollers 23 arejournaled at 9AY in the flanges and are, therefore, always re tained intheir proper relative positions.

The. plate 8 is, however, providedwith vdownwardly extending ribs 25 onits two.

Y and the downwardly extending portions 17 ot the carrier iron 'i6 actas stops to limit the movement of the plate 3- longitudinally of thecarrier iron. f

it will be apparent that various changes may be made in the form,construction and arrangement oi the parts without departingr from thespirit and scope ot' the invention or sacrificing any of its materialadvantages, the forms hereinl'iefore disclosed being merely preferredembodiments thereof.
